good guess - but no!! And now it's 3am, I'm off to bed

actually, if there's a ball, it's unusual, the sport isn't considered a ball sport, the ball itself isn't usually noticed... (Might be if it's not there; I don't know. I'll research when I wake. If I remember)

Well, I checked: no ball.

OK, when you wake up, does the sport require a pool?

Is it a non-traditional Olympics like the Paralympics or Special Olympics?

No water involved.

Yes to Olympics.

Yes to Paralympics.
